Description

Technical Field

[0001] This utility model relates to the field of tire forming machines, and more specifically, to a tire blank transfer device and a forming machine. Background Technology

[0002] Traditional one-step forming machines for passenger radial tires require manual removal of the tire blank from the transfer ring, followed by manual transport to the weighing station for weighing and defect detection. After weighing, the tire blank is then manually transferred to a tire blank cart. Since tire sizes typically range from 14 to 24 inches, with tire blanks weighing between 7 and 40 kg, the process is relatively heavy. Manual removal, transport, and weighing of the tire blanks results in low production efficiency and high labor intensity. While current automated transfer and weighing devices can automatically transfer tire blanks between multiple stations, unavoidable abnormalities such as tire rollover or tilting during transfer can easily cause collisions with other structural components, leading to distorted weighing results and potential damage to the tire blank or equipment, thus affecting production efficiency and product quality. Utility Model Content

[0003] The main purpose of this utility model is to provide a fetal embryo transfer device and a molding machine to solve the problem of poor weighing accuracy of existing fetal embryo transfer devices.

[0004] To achieve the above objectives, according to one aspect of the present invention, a tire-embryo transfer device is provided, comprising a base, a lifting mechanism, a weighing mechanism for weighing the tire-embryo, and a tire-embryo basket. The lifting mechanism is vertically connected to the base; the weighing mechanism is connected to the base; the tire-embryo basket has a receiving position, a weighing position, and a repair position; the lifting mechanism is intermittently driven to the tire-embryo basket and drives the tire-embryo basket to switch between the receiving position, the weighing position, and the repair position; when the tire-embryo basket is in the receiving position or the repair position, the lifting mechanism is driven to the tire-embryo basket; when the tire-embryo basket is in the weighing position, the lifting mechanism is driven to separate from the tire-embryo basket, and the weighing mechanism weighs the tire-embryo.

[0005] Furthermore, the lifting mechanism includes a transmission component and a drive component. The transmission component is movably connected to the tire basket. When the tire basket is in the tire receiving position or the tire repair position, the transmission component is driven to connect with the tire basket. When the tire basket is in the weighing position, the transmission component is separated from the tire basket. The drive component is driven to connect with the transmission component and drives the transmission component to switch the tire basket between the tire receiving position, the weighing position, and the tire repair position.

[0006] Furthermore, when the tire basket is located in the tire repair position, tire connection position, and weighing position, the height of the tire basket decreases sequentially.

[0007] Furthermore, the bottom of the embryo basket has a V-shaped structure.

[0008] Furthermore, the bottom of the tire blank basket includes multiple support rollers, all of which form a V-shaped structure.

[0009] Furthermore, the embryo transfer device also includes a protective element connected to the base. The embryo basket has an inlet side for the embryo to enter, and the protective element is located on the inlet side. The embryo enters the embryo basket through the protective element.

[0010] Furthermore, the protective component is rotatably connected to the base. When the tire basket is in the tire receiving position, the protective component is rotatably rotated to a lateral position and carries the tire, and the protective component is higher than the lower edge of the inlet side.

[0011] Furthermore, the embryo transfer device also includes a safety protection component, which is connected to the base and detects personnel around the base. The safety protection component is electrically connected to the lifting mechanism and shuts down the lifting mechanism when personnel are detected approaching.

[0012] Furthermore, the embryo transfer device also includes a weight monitoring device, which is electrically connected to the weighing mechanism and monitors the weight of the embryo.

[0013] According to another aspect of the present invention, a molding machine is provided, including the above-described embryo transfer device.

[0014] By applying the technical solution of this utility model, a lifting mechanism and a weighing mechanism are set up to achieve efficient transfer and accurate weighing of tire blanks, thereby improving weighing accuracy, reducing manual intervention, and improving production efficiency and safety. Specifically, on the one hand, the lifting mechanism and the tire blank basket are intermittently driven to separate when the tire blank is weighed at the weighing position. This allows the tire blank weighing process to be completed within the tire blank basket, thus avoiding collisions with surrounding structural components or even falling off when the tire blank is tilted, overturned, or skewed, ensuring the accuracy of the tire blank weighing results and improving production efficiency. On the other hand, the lifting mechanism drives the tire blank basket to switch between the tire receiving position, the weighing position, and the tire repair position, thereby realizing automatic transfer of the tire blank between different work positions such as tire receiving, weighing, and tire repair. This improves work efficiency, reduces the labor intensity of operators, increases the level of automation, and avoids the safety risks that occur during manual tire receiving, tire blank handling, and manual weighing.

[0029] To address the problem of poor weighing accuracy in existing embryo transfer devices, this invention provides an embryo transfer device and a molding machine, wherein the molding machine includes the embryo transfer device described below.

[0030] like Figures 1 to 8 The device shown includes a tire-embryo transfer device, comprising a base 10, a lifting mechanism 20, a weighing mechanism 30 for weighing the tire-embryo, and a tire-embryo basket 40. The lifting mechanism 20 is vertically connected to the base 10; the weighing mechanism 30 is connected to the base 10; the tire-embryo basket 40 has a tire receiving position, a weighing position, and a tire repair position. The lifting mechanism 20 is intermittently driven to connect with the tire-embryo basket 40 and drives the tire-embryo basket 40 to switch between the tire receiving position, the weighing position, and the tire repair position. When the tire-embryo basket 40 is in the tire receiving position or the tire repair position, the lifting mechanism 20 is driven to connect with the tire-embryo basket 40; when the tire-embryo basket 40 is in the weighing position, the lifting mechanism 20 is driven to separate from the tire-embryo basket 40, and the weighing mechanism 30 weighs the tire-embryo.

[0031] This embodiment achieves efficient transfer and accurate weighing of tire blanks by setting up a lifting mechanism 20 and a weighing mechanism 30, thereby improving weighing accuracy, reducing manual intervention, and improving production efficiency and safety. Specifically, on the one hand, the lifting mechanism 20 and the tire blank basket 40 are intermittently driven to connect, so that when the tire blank is weighed at the weighing position, the tire blank basket 40 and the lifting mechanism 20 are driven to separate, so that the weighing process of the tire blank is completed in the tire blank basket 40. This avoids collisions with other structural components or even falling off when the tire blank is tilted, overturned, or deviated, thus ensuring the accuracy of the tire blank weighing results and improving production efficiency. On the other hand, the lifting mechanism 20 drives the tire blank basket 40 to switch between the tire receiving position, the weighing position, and the tire repair position, thereby realizing automatic transfer of the tire blank between different work positions such as tire receiving, weighing, and tire repair. This improves work efficiency, reduces the labor intensity of operators, improves the level of automation, and avoids the safety risks that occur during manual tire receiving, tire blank handling, and manual weighing.

[0032] like Figures 1 to 4As shown, in this embodiment, the lifting mechanism 20 includes a transmission component 21 and a driving component 22. The transmission component 21 is movably connected to the tire basket 40. When the tire basket 40 is in the tire receiving position or the tire repair position, the transmission component 21 is driven to connect with the tire basket 40. When the tire basket 40 is in the weighing position, the transmission component 21 is separated from the tire basket 40. The driving component 22 is driven to connect with the transmission component 21 and drives the transmission component 21 to switch the tire basket 40 between the tire receiving position, the weighing position, and the tire repair position. This ensures both the flexibility of the tire basket 40 switching between different positions and the accuracy of the weighing results. Specifically, optionally, the driving component 22 can be a geared motor, and the transmission component 21 includes a synchronous pulley, a synchronous belt, and a slider. The transmission component 21 is vertically connected to the base 10, which has a guide rail. The slider is located within the guide rail and can move along the guide rail. The geared motor drives the slider to move up and down along the guide rail via the synchronous belt and the synchronous pulley, thereby driving the tire basket 40 to move up and down. The transmission component 21 has a support member on the side facing the tire basket 40 to support the lifting and lowering movement of the tire basket 40. The support member is fixed to the slider and engages with the bottom of the tire basket 40, with the tire basket 40 positioned above the support member. The tire basket 40 can engage with the support member through gravity or through a force-activated separation method such as magnetic attraction or snap-fit. The support member can be configured as a support plate structure that engages with the lower surface of the tire basket 40, or it can be configured as a support frame structure that engages with the peripheral edge of the bottom of the tire basket 40. When the transmission component 21, driven by the drive component 22, moves the tire basket 40 up and down between the tire receiving position and the tire repair position, the bottom of the tire basket 40 remains in contact with the support component. When the transmission component 21 moves the tire basket 40 from the weighing position to the weighing position, the tire basket 40 is blocked by the weighing mechanism 30 after reaching the weighing position and stops moving. The support component can avoid the position of the weighing mechanism 30, so that the transmission component 21 can continue to move downward and separate from the tire basket 40. In this way, when the weighing mechanism 30 weighs the tire basket 40, the tire can be accurately weighed without the influence of the lifting mechanism 20. Moreover, the tire is placed in the tire basket 40 for weighing, which avoids the tire tilting and colliding with other structural components around it and affecting the weighing result, thereby improving the accuracy of the weighing result. After the tire carcass is weighed, the transmission component 21 moves upward under the drive of the drive component 22. When it reaches the weighing position, it engages with the bottom of the tire carcass basket 40, thereby driving the tire carcass basket 40 upward away from the weighing position. Of course, the engagement method between the transmission component 21 and the tire carcass basket 40 is not limited to this. The bottom of the transmission component 21 may not be a support structure, but may be a hook-shaped structure. The hook-shaped structure also engages with the bottom of the tire carcass basket 40, providing stable support for the tire carcass basket 40. When the tire carcass basket 40 reaches the weighing position, it can avoid the position of the weighing mechanism 30 and continue to move downward until it separates from the tire carcass basket 40. The drive component 22 may also be a cylinder, electric cylinder, or other drive methods.

[0033] In this embodiment, when the tire basket 40 is located at the tire trimming position, tire receiving position, and weighing position, the height of the tire basket 40 decreases sequentially. Thus, during the process of the tire basket 40 moving from the tire trimming position to the tire receiving position and then to the weighing position, the gravity of the tire helps stabilize the tire, reducing swaying during transport and improving the stability and safety of the tire transfer device. This also helps to simplify the structure of the tire transfer device and effectively utilizes vertical space, thereby improving space utilization. Considering the lifting mechanism 20 and the driving method of the tire basket 40 in this embodiment, the weighing position is located below the tire trimming and tire receiving positions. The positions of the tire trimming and tire receiving positions can be changed according to actual needs.

[0034] In this embodiment, the bottom of the embryo basket 40 has a V-shaped structure, which better adapts to the shape of the embryo, providing more stable support and reducing swaying during transport, thus effectively preventing the embryo from tipping over. Specifically, the embryo basket 40 in this embodiment includes a basket bottom and two side fixing frames. These fixing frames are respectively located on opposite sides of the basket bottom to prevent the embryo from tipping out of the basket 40. The V-shaped structure refers to a structure that is lower in the middle and higher at both ends. In this embodiment, the projection of the embryo basket 40 onto the horizontal plane is rectangular, with two opposite edges connected to the fixing frames. The other two opposite edges are the higher ends of the V-shaped structure. This creates a self-centering structure at the bottom of the basket, allowing the embryo to automatically move to a position less prone to swaying when it enters the basket 40, thereby reducing swaying during transport and preventing tipping. Alternatively, the basket bottom can also be designed as an arc-shaped structure that is lower in the middle and higher around the edges, which can also reduce swaying and tilting of the embryo during transport.

[0035] In this embodiment, the bottom of the tire blank basket 40 includes multiple support rollers 41, all of which form a V-shaped structure. This reduces the frictional force when the tire blank moves within the basket 40, helping it to quickly move to the appropriate position when it falls into the basket 40 and reducing tire blank swaying. Preferably, the support rollers 41 are rotatable, further reducing tire blank swaying within the basket 40 and improving the stability of the tire blank and the basket 40.

[0036] like Figures 5 to 8As shown, in this embodiment, the tire embryo transfer device further includes a protective member 50, which is connected to the base 10. The tire embryo basket 40 has an entrance side for the tire embryo to enter. The protective member 50 is disposed on the entrance side, and the tire embryo enters the tire embryo basket 40 through the protective member 50, thereby preventing the tire embryo from accidentally slipping when entering the tire embryo basket 40, thus improving operational safety. Specifically, the entrance side of the protective member 50 is located between two fixed frames. The protective member 50 is configured as a rectangular plate, and the edge of the protective member 50 is connected to the entrance side of the tire embryo basket 40, thereby expanding the space range for the tire embryo basket 40 to receive the tire embryo, preventing the tire embryo from falling to the ground, and thus improving the success rate of the tire embryo basket 40 in receiving the tire embryo.

[0037] In this embodiment, the protective member 50 is rotatably connected to the base 10. When the tire basket 40 is in the receiving position, the protective member 50 flips to a lateral position and carries the tire. This allows the protective member 50 to assist the tire basket 40 in receiving the tire, and when the tire basket 40 is not receiving the tire, the protective member 50 can flip to a vertical position or other angle, thus avoiding space occupation. In this embodiment, the protective member 50 is higher than the lower edge of the inlet side, ensuring that the tire falls onto the protective member 50 and slides into the tire basket 40 on its own, thus saving manpower.

[0038] like Figure 6 As shown, in this embodiment, the tire blank transfer device also includes a safety protection component 60. The safety protection component 60 is connected to the base 10 and detects personnel around the base 10. The safety protection component 60 is electrically connected to the lifting mechanism 20 and shuts down the lifting mechanism 20 when personnel are detected approaching. This effectively prevents operators from approaching the equipment during operation, preventing safety accidents, improving production safety, and protecting the lives of operators. Optionally, the safety protection component 60 can be a safety light curtain. In this embodiment, two safety protection components 60 are provided, both located at the bottom of the base 10, and the two safety protection components 60 are positioned opposite each other on both sides where the fixing frame is installed. The tire blank transfer device in this embodiment can adopt an integrated safety protection design, which not only includes a safety light curtain but also a safety guard plate located around the base 10, thereby providing safety protection for the internal tire blank basket 40, lifting mechanism 20, etc., further reducing safety risks.

[0039] In this embodiment, the fetal embryo transfer device also includes a weight monitoring component 70, which is electrically connected to the weighing mechanism 30 and monitors the weight of the fetal embryo. This allows for timely detection of abnormal fetal embryo weight, thereby improving weighing accuracy and production efficiency. The weight monitoring component may include a digital weighing display device, a weighing alarm device, etc. After the weighing mechanism 30 completes weighing, the digital weighing display device shows the weighing result. If there is an abnormal weight, the weighing alarm device will promptly sound an alarm to notify the staff of the fetal embryo abnormality, thereby improving the effectiveness of the weighing results.

[0040] The tire blank transfer device in this embodiment is also equipped with a lighting component and a host computer display screen. The lighting component is connected to the base 10 and is located at the tire repair position to facilitate tire repair by the operator. The host computer display screen can be electrically connected to the control system of the molding machine, thereby enabling information exchange with other components of the molding machine and facilitating the operator to obtain the operating status of the tire blank transfer device.

[0041] The embryo transfer device in this embodiment integrates multiple functions such as switching between three workstations, weighing, digital weighing display, weighing alarm, lighting, and host computer display screen, thereby realizing the integration of multiple information reception and output and multi-functional operation, making human-machine assistance more reasonable and operation more convenient.

[0042] The usage process of the tire-carrying embryo transfer device in this embodiment is as follows: 1. The driving component 22 drives the transmission component 21 to move the tire-carrying embryo basket 40 to the tire receiving position; 2. The tire unloading device of the transfer ring unloads the tire, and the tire-carrying embryo rolls into the tire-carrying embryo basket 40 after passing through the protective component 50. The tire-carrying embryo basket 40 achieves automatic centering after the tire-carrying embryo rolls down through the V-shaped structure; 3. The driving component 22 drives the transmission component 21 to move the weighing basket and the tire-carrying embryo downwards simultaneously to the weighing position for weighing. The driving component 22 drives the transmission component 21 to continue moving downwards until it separates from the tire-carrying embryo basket 40; 4. After the weighing is completed, the driving component 22 drives the transmission component 21 to rise to the weighing position. The transmission component 21 is connected to the tire-carrying embryo basket 40 and continues to drive the tire-carrying embryo basket 40 and the tire-carrying embryo to rise to the tire repair position; 5. The operator pulls the tire-carrying embryo to the tire repair position for tire inspection.

[0043] It should be noted that "multiple" in the above embodiments refers to at least two.

[0044] As can be seen from the above description, the embodiments of this utility model achieve the following technical effects:

[0045] 1. This technology solves the problem of poor weighing accuracy in existing embryo transfer devices;

[0046] 2. By setting up lifting and weighing mechanisms, efficient transfer and accurate weighing of the embryo can be achieved, thereby improving weighing accuracy, reducing manual intervention, and improving production efficiency and safety.

[0047] 3. The intermittent drive connection between the lifting mechanism and the tire basket allows the tire basket and the lifting mechanism to separate when the tire is being weighed at the weighing position. This ensures that the weighing process of the tire is completed in the tire basket, thus preventing the tire from colliding with other structural components or even falling off when there are abnormalities such as tilting, tipping, or skewing. This ensures the accuracy of the tire weighing results and improves production efficiency.
